Description

The present invention relates to a head guide member, a printing device, and a method for manufacturing the head guide member.

As a printing device that prints on a medium, for example, an inkjet type printing device that ejects droplets from a head onto the medium is known (see, for example, Patent Document 1). Such a printing device has, for example, a mounting table on which media can be placed, a head that ejects droplets toward the surface of the media while reciprocating on the mounting table in the main scanning direction, and a head in the main scanning direction. It is provided with a head guide member for guiding the head and a relative moving portion for relatively moving the head and the mounting table in the sub-scanning direction intersecting the main scanning direction.

In such a printing apparatus, the head guide member is formed by attaching a guide member to a frame extending in the main scanning direction. As the frame, for example, a frame obtained by cutting an extruded metal such as aluminum, a frame obtained by bending a metal plate, or the like is used.

Japanese Unexamined Patent Publication No. 2015-13455

However, a frame obtained by cutting an extruded product is expensive. In addition, in a frame made by bending a metal plate, it is possible to secure a certain degree of accuracy by correcting the mounting surface of the guide member, but it is difficult to directly cut the mounting surface to ensure flatness, so it is high. It is difficult to improve the accuracy.

The present invention has been made in view of the above, and an object of the present invention is to provide a head guide member, a printing device, and a method for manufacturing a head guide member, which can guide a head with high accuracy at low cost.

The head guide member according to the present invention is a head guide member provided in a printing apparatus provided with a head for ejecting ink toward a work surface and guides the head in the main scanning direction, and is a frame extending in the main scanning direction. , A base member having a guide reference surface which is plate-shaped, fixed to the frame, and processed to be a flat surface along the main scanning direction while being fixed to the frame, and a base member having a guide reference surface in the main scanning direction. It is provided with a guide member that extends and is supported by the guide reference surface of the base member to guide the head in the main scanning direction.

According to this configuration, the guide reference surface of the base member is processed into a flat surface along the main scanning direction based on the configuration in which the base member is attached to the frame. Therefore, the guide reference surface of the base member is processed. Therefore, the flatness of the guide reference plane can be easily ensured regardless of the shape of the frame. Further, since the guide member is supported by the guide reference surface processed into a plane along the main scanning direction while being fixed to the frame, the guide member can be arranged with high accuracy along the plane. This makes it possible to obtain a head guide member capable of guiding the head with high accuracy at low cost.

Further, a plurality of the base members may be arranged at intervals in the main scanning direction, and the guide members may be provided across the plurality of the base members.

As a result, it is possible to reduce the influence of expansion and contraction due to thermal deformation at the end portion of the base member in the main scanning direction while arranging the guide member with high accuracy along the plane.

Further, the base member may have a plurality of recesses in the main scanning direction on the frame contact surface that is in contact with the frame.

As a result, stress due to thermal deformation can be released at the center of the frame in the main scanning direction.

Further, the base member may have a slit portion connecting the end side in the direction intersecting the main scanning direction and the recess on the frame contact surface.

As a result, the stress due to thermal deformation can be more reliably released in the central portion of the frame in the main scanning direction.

Further, the guide member may be fixed to the frame by a fixing member provided so as to penetrate the base member.

By fixing the guide member to the frame in this way, it is possible to prevent the fixing member from being directly fixed to the base member as much as possible, so that deformation of the base member can be suppressed. As a result, the frame can be formed of a highly rigid material, and a material that is softer than the frame and can be easily processed to form a guide reference surface can be selected as the base member.

Further, the frame may be formed in a state where the metal plate is bent.

As described above, even when the frame in which the metal plate is bent is used, the head can be guided with high accuracy, so that the frame can be formed at low cost.

Further, the printing device may have a housing, and the frame may be a part of the housing of the printing device.

As a result, the rigidity of the frame contributes to the rigidity of the housing of the printing device, so that the rigidity of the housing of the printing device can be increased.

Further, the processing may be a cutting processing.

Thereby, a guide reference plane having a high flatness can be easily formed.

The printing apparatus according to the present invention includes a head that ejects ink toward a work surface, a head guide member according to any one of claims 1 to 6, which guides the head in the main scanning direction. A drive unit for driving the head in the main scanning direction along the head guide member is provided.

As a result, the head can be guided with high accuracy by using the head guide member, so that high-precision printing can be performed.

The printing apparatus according to the present invention is a method for manufacturing a head guide member provided in a printing apparatus provided with a head for ejecting ink toward a work surface and guiding the head in the main scanning direction, and extends in the main scanning direction. A guide for fixing a plate-shaped base member to a frame and a guide for forming a guide reference surface by processing one surface of the base member into a flat shape along the main scanning direction while being fixed to the frame. It includes a reference surface forming step and a guide member supporting step of supporting the guide member for guiding the head on the guide reference surface.

As a result, the guide reference surface can be formed with high accuracy and efficiency by processing one surface of the base member fixed to the frame into a flat surface along the main scanning direction.

Further, in the guide reference surface forming step, the guide reference surface may be formed by cutting.

Thereby, a guide reference plane having a high flatness can be easily formed.
